The well-advertised unsettled weather pattern is arriving for the weekend. There will be periodic chances of storms. This includes the likelihood of some embedded storm within showers in parts of north central and central Illinois this afternoon. Scattered storms are then possible tonight, though much of them look to stay south and west of Chicago. There is a limited severe weather threat with these, but cannot be ruled out especially south of I-80.
Temperatures look to inch upward this weekend with humid air also arriving. Saturday afternoon and early evening look to have a minimum in thunderstorm coverage, but then coverage should increase later into Saturday night. There will be a limited severe weather threat for Saturday and Saturday night along with some flooding risk Saturday night.
